Slow rendering performance in Windows 10

[SK9985]

Hi,

I'm experiencing slow rendering performance in some apps. I noticed that primarily WPF based apps perform poorly. After tinkering around a bit I decided to disable 3D acceleration. This seemed to "restore" rendering performance for the WPF based apps but rendering in general seems now a bit more sluggish.

Also boot performance (APFS drive) is really slow and working with a volume shared from the Mac is also painfully slow (working with source code and compiling in Visual Studio). I could workaround the latter by moving the source files to the Windows "internal" drive.

Coming from Parallels (where I also had massive perf issues), it's still better but I was wondering if vmware will address these issues sooner or later. I did some research in the forum and I can see that most issues I'm experiencing are known for > 1 year sometimes.

I'm running my vm on vmware Fusion 11 on an iMac Pro (plenty of CPU and RAM left for macOS).

Regards,
Stefan

Similar issue in Visual Studio XAML designer.

I just installed Parallels 16 and boy, the rendering performance is awesome. All their claims are true I guess. Regardless if it's a WPF app or a Chromium/Electron app (OpenGL) like VS Code. Window rendering, resizing, maximizing/restoring is so much faster - almost instant and comparable to native performance.

I have to say, vmware needs to get their act together and provide similar DirectX and OpenGL performance. For now I will keep running Parallels and once vmware caught up, I'm happy to switch back as licensing is still much "friendlier" in vmware...

The latest Tech Preview may help, learn more here: VMware Fusion Pro Tech Preview

I've seen that, thanks. I will gladly try that once it has been "officially" released. I'm hesitant to install a "Tech Preview" on my production machines unless this is fully supported and considered stable. Any information when this will be released?

Before the end of the year - nothing more specific has been announced.
